Comment top

Carbonohydrazide derivatives are popular ligands in coordination chemistry due to the strong coordinative ability (Esmail et al., 1977). Meanwhile, they have also attracted much attention due to interesting bioactivity such as antibacteriale antifungal, anticonvulsant, anticancer activities (Loncle et al., 2004). Herewith we present the crystal structure of the title compound, (I), which is a carbonohydrazide derivative.

In (I) (Fig. 1), the bond lengths and angles are normal and comparable to those observed in the reported compound (Meyers et al., 1995). The C=N bond lengths in the molecule are 1.282 (5) °, 1.272 (5)° (C2=N5, C1=N11), respectively, showing the double-bond character. The dihedral angle between the benzene ring (C12—C17) and the plane of C11/N1/N2 is 19.17 (27) °, while the dihedral angle between the benzene ring (C3—C8) and the plane of C2/N5/N6 is 14.87 (31) °.

Intermolecular N—H···O and N—H···N hydrogen bonds (Table 1) link the molecules into paired ribbons propagated in direction [100].

Experimental top

Acetophenone (10.0 mmol) and carbohydrazide (10.0 mmol) were mixed in 50 ml flash under sovlent-free condtions. After stirring 2 h at 373 K, the resulting mixture was cooled to room temperature, and recrystalized from ethanol, and afforded the title compound as a crystalline solid. Elemental analysis: calculated for C₉H₁₂N₄O: C 56.24, H 6.29, N 29.15%; found: C 56.13, H 6.24, N 29.31%.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
